Not sure how deep the hardening goes. The gears could be made from hardened metal, or just the surface could be hardened. That's probably something you'd have to contact RR for to get a definitive answer.
In the meantime, you could simply use the stock second gear and use the rest of the metal gears until you come up with a solution for the steel gear issue. Yeah, it's not as good, but at least you'd be up and running until then.

Sorry, that's probably my fault.
